I'll begin by saying that since the MBP is way overdue for an update, and a laptop isn't a necessity at this time, I will probably wait to see if something new comes out in the next few weeks. Having said that, if I did decide to get a new laptop now, with the exception of screen size, what would the difference be between a low-end MBP and the higher end MB? I'd get 2 GB of RAM which ever laptop I'd get, and the hard drive would also be the same size (250 GB). Also, what is the difference between a 2.2 GHz and 2.4 GHz? What applications would have a noticeable difference? I'm leaning towards the MBP now after not being able to make a decision between the black or white MB.
